php获取搜索引擎爬虫蜘蛛

直接上代码：

function isbot($tmp) {
    // 定义蜘蛛识别规则集（保持原顺序）

以下是判断客户端访问类型：

function ClientType() {
    // 安全获取 HTTP 头部信息
    $userAgent = $_SERVER['HTTP_USER_AGENT'] ?? '';
    $httpAccept = $_SERVER['HTTP_ACCEPT'] ?? '';

    // 优先检测蜘蛛类型
    if ($botType = isbot($userAgent)) {
        return "蜘蛛：" . $botType;
    }

    // 非蜘蛛设备分类逻辑
    if (stripos($httpAccept, 'text/html') !== false) {
        return "访客";
    }

    // API 客户端、爬虫工具等特殊类型
    // 常见爬虫工具列表
    $crawlerTools = [
        'curl' => 'cURL命令行工具',
        'wget' => 'Wget下载工具',
        'python' => 'Python爬虫',
        'java' => 'Java爬虫',
        'php' => 'PHP爬虫',
        'perl' => 'Perl爬虫',
        'ruby' => 'Ruby爬虫',
        'go-http-client' => 'Go爬虫',
        'node-fetch' => 'Node.js爬虫',
        'libwww' => 'libwww-perl工具',
        'okhttp' => 'OkHttp客户端',
        'http-client' => 'HTTP客户端',
        'apache-httpclient' => 'Apache HTTP客户端',
        'axios' => 'Axios HTTP客户端',
    ];
    // 检查爬虫工具
  foreach ($crawlerTools as $key => $name) {
        if (stripos($userAgent, $key) !== false) {
            return $name;
        }
    }

    // 默认未知类型
    return "未知";
